“Don’t ever do this.” “You should never do that.” We’ve all heard certain decorating rules regarding colors, furniture, finishes and accessories. But how many of these are actually true, and how many may have made sense in the past but are no longer applicable? We asked a few experts to weigh in and separate fact from fiction.

This rule is true, according to Kimberly Schmunk, an interior designer at Nashville-based luxury custom home developer Focus Builders. “I tend to lean toward a more soothing color palette in the bedroom, since this is the room you will be winding down in.” If you want to incorporate bold colors, she recommends including it in artwork, throw pillows or other accessories. You can paint your bedroom bright red, but don’t be surprised if you struggle to fall asleep at night.

Some people warn homeowners against using stainless steel because it shows fingerprints and is harder to clean. However, Schmunk says that this shouldn’t be a problem if you use cleaning products formulated for stainless steel (she recommends Steel Meister Stainless Steel Cleaner). Some stainless steel manufacturers make it even easier; they recommend using warm, soapy water on a damp cloth, followed by a final rinse with clean water. (Note: steel wool should never be used on any type of stainless steel.)

“I don’t think you can go wrong with builder beige, as it is very neutral and will not scare off buyers,” says Mark Ferguson, a real estate agent, real estate investor, author and the creator of Invest Four More. However, he says that this is not the only color you can use. “Light grays can look very good and are in fashion right now — we even try some colors with hints of blue or green.” However, Ferguson warns against using colors that are too dark or too bright. Fortunately, there’s a way to paint over bolder colors using fewer coats of paint.

Should you use small furniture in small rooms?

Decorating rules - furniture size

The scale and proportion of your furniture can make or break the design, warns Schmunk. “I suggest including smaller pieces in a small space; otherwise, it may feel like your selection was an afterthought.”

However, Texas-based designer Pablo Solomon says that using fewer pieces of furniture that have multiple functions are better than using a lot of small pieces. When you have a small room, Solomon offers these three tips:

  • Maintain the longest lines of sight you can to windows and to other rooms
  • Do not block windows
  • Use see-through furniture (acrylic, glass) near windows of contemporary homes

One of the most repeated decorating rules is to avoid mixing metals. However, Schmunk says that it’s perfectly fine to mix metals, as long as you limit the number of metals to about two. Solomon agrees, though with a caveat: “Any décor details must work together in a given setting. Mixing metals may work in one setting and be an eyesore in another.” Studying the latest faucet trends and bathroom technology can help you decide which elements work well together.

This is one of the oldest tricks in the book. Mirrors reflect light, making a room look larger and brighter. This is particularly important when you’re using dark colors in a small room.

Another rule refers to using the color black, and some people shy away from this color. However, black is the most stylish color of every year, and it is being used as a statement color, and to highlight windows, celings, and doors.

Whatever you dream about for your new design, chances are there’s a way to make it happen. Solomon says that he is not a firm believer in decorating rules. “My only rule is to have a finished space that is balanced, proportionate, functional, eye-pleasing and tells the story that you want to tell.” Which decorating rules have you followed or broken in creating your dream home?
